ENVELOP OR THE LIKE.

SPECIFICATION forming part of Letters Patent N 0. 743,314, datedNovember 3, 1903.

Application filed February 6, 1903. Serial No. 142,229. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM MYERs,a subject of the King of GreatBritain, residing in v sists in the improved construction, arrangement,and combination of parts hereinafter dcscribed,and afterwardspecifically claimed.

The invention will be described with reference to the accompanyingdrawings, in which-- Figures 1 to 3 are plans of envelop-blanks;

Fig. 4C, a plan of a partlyformed envelop Fig. 5, a perspective view ofa fully-formed envelop; and Fig.6 aface view of Fig. 5, but with themouth closed. Fig. 7 is a perspective view showing the manner of foldingthe Fig. 1 shows the broken edges produced by a series of short cuts a,forming tongues.

Fig. 2 shows an envelop provided with a broken edge consisting of acombination of the serrations a and cuts a. The broken form may run thewhole length of the edge on which it is provided, as shown in Fig. 2, oronly partially along the edge at required places, as shown in Fig. 3.The shaded parts in all the figures indicate the adhesive.

In practice I prefer to provide an additional folded edge A, as shown inFigs. 2 and 3, to receive this broken form of my invention, and I securethe serrated or broken edge ato. the main folding-edge B with anadhesive, as shown in Fig. 4, before folding the two edges A B over ontothe back of the envelop, to which both folded parts A B are secured bymeans of an adhesive, as shown in Fig. 5.

In carrying the invention into effect the serrated or broken edge may beformed on either the underlying or overlying flap or edge.

I provide the mouth of the envelop with a flap, tongue, or otherprojection G on the edge opposite to the existing fiap D and forming aslot 0 in the crease line of the latter. The

envelop is closed with this arrangement by the flap C on the oppositeand exterior surface of the envelop, as shown in Fig. 6. The envelopthus closed can be readily opened by inserting a finger or a knife orimplement in the slot 0 and running it along the whole edge to tear itopen, while before opening the auxiliary flap O prevents the contentsfrom being inspected through the slot 0 and also strengthens the envelopat this point. In some cases I may form the auxiliary flap or tongue 0to extend the whole length of the mouth, as shown in Fig. 2, and simplycut it in two placese e to form a tongue near the middle to be passedthrough the slot 0 of the ordinary fiap D. In this way I provideadditional flaps E E on each side of the tongue 0, and these, whetherserrated in accordance with the first part of this invention, as shownin Fig. 5, or left with a straight edge, as shown coat whereby they maybe secured to the main flap D, as shown in Fig. 7, and then all turneddown, together with the flap D, onto the envelop in the act ofclosing,as shown by the dotted arrows, thus providing a furtherstrengthening of the closing of the mouth.

I declare that what I claim is- 1. An envelop or the like, consisting ofa blank having a broken-edged flap along one edge and a flap along theother, both flaps being coated with adhesive material, the blank beingfolded along the middle with the brokenedged flap secured to the flap onthe other edge,and the last-named flap with the brokenedged flap beingfolded over upon and secured to the main body of the envelop.

2. A blank for an envelop adapted to be folded in the center andprovided along its opposite edges respectively with flaps and coated onthe same face with adhesive material, one of said flaps having a brokenedge and being adaptedto be secured by its adhesive material upon theface of the other flap .80 in Fig. 2, are adapted to receive an adhesivein the first folding of the blank to form the envelop.

3. In an envelop or the like, the combination with the usualmouth-closing flap, of a slot in the crease-line of same, a tongueforming an auxiliary flap on the opposite edge of the mouth, andadditional flaps on said edge on each side of the tongue, said tonguebeing adapted to be passed through the slot and stuck down onto theopposite exterior face of the envelop, and the additional flaps beingadapted to have one face stuck to the usual flap and the other face tothe body of the envelop when the usual flap is stuck down, substantiallyas described.

4. In an envelop or the like, the combination with the usualmouth-closing flap, of a slot in the crease-line of same, a tongueforming an auxiliary flap on the opposite edge of the mouth, andadditional flaps on said edge on each side of the tongue, said tonguebeing adapted to be passed through the slot and stuck down onto theopposite exterior face of the envelop, and the additional flaps beingadapted to have one face stuck to the usual flap and the other face tothe body of the envelop whenthe usual flap is stuck down, the edges tobe stuck down having a broken form at desired parts to afford securityagainst being lifted, substantially as described.

5. An envelop or the like comprising a folded blank in which theunderlying one of the meeting edges of same has a broken form, and anadditional fold back onto itself beneath the other edge, the additionalfold and the overlying edge being secured by an adhesive one to theother and both to the body of the envelop, a mouth-closing flap having aslot in its crease-line, and an auxiliary flap on the opposite edge ofthe mouth adapted to be passed through said slot and stuck down onto theopposite exterior face of the envelop,

substantially as described.

6. An envelop or the like comprising a folded blank in which theunderlying one of the meeting edges of same has a broken form,

and an additional fold back onto itself beneath the other edge, theadditional fold and the overlying edge being secured by an adhesive oneto the other and both to the body of the envelop, a mouth-closing flaphaving a slot in its crease-line, a tongue forming an auxiliary flap onthe opposite edge of the mouth, and additional flaps on said edge oneach side of the tongue, said tongue being adapted to be passed throughthe slot and stuck down onto the opposite exterior face of the envelopand the additional flaps being adapted to have one face stuck to theusual flap and the other face to the body of the envelop when the usualflap is stuck down, substantially as described.

7. An envelop or the like comprising a folded blank in which theunderlying one of the meeting edges of same has a broken form, and anadditional fold back onto itself beneath the other edge, the additionalfold and the overlying edge being secured by an adhesive one to theother and both to the body of the envelop, a mouth-closing flap having aslot in its crease-line, a tongue forming an auxiliary flap on theopposite edge of the mouth, and additional flaps on said edge on eachside of the tongue, said tongue being adapted to be passed through theslot and stuck down onto the opposite exterior face of the envelop, andthe additional flaps being adapted to have one face stuck to the usualflap and the other face to the body of the envelop when the usual flapis stuck down, the edges to be stuck down in the closing having abrokenform at desired parts to afford security against being lifted,substantially as described. I

In witness whereof I have hereunto signed my name, this 28th day ofJanuary, 1903, in
